Technology At Verretec

By combining a vertically integrated manufacturing platform with the latest glass melting and textile technologies, Verretec's products are able to surpass many of the traditional performance standards of continuous glass reinforcements.

FlatFiber™ Technology

Verretec’s unique FlatFiber™ yarn strand removes the twist, eliminating the destructive and costly yarn twisting operation in the manufacturing process. The result is a flat, ribbon-like glass strand that is not only stronger than twisted glass, but yields numerous technical advantages as a composite reinforcement.

Thin, Smooth, Uniform Glass

Verretec’s FlatFiber™ yarn yields a thinner, smoother, truly isotropic glass fabric. Fiber voids and weave knuckles are minimized, and the physical properties in the X and Y directions are exceptionally uniform.

Thin, Smooth, Uniform Composites

Stronger Glass Fabric

For the same weight and construction, Verretec’s FlatFiber™ glass fabrics are stronger than glass fabrics made with twisted yarns. For the most demanding applications we offer VerreStrong™ glass fabric. VerreStrong™, made with E² glass (a proprietary process enhanced E-glass designed to deliver superior strength), is significantly stronger than traditional E-glass fabric, and even stronger than many costly glass fabrics made with so called high strength (non E-glass) compositions.

Stronger Laminates with VerreStrong™

Due to its superior tensile strength, laminates produced with VerreStrong™ glass fabric outperform laminates made with traditional E-glass fabrics.

Improved Electrical & Thermal

Verretec’s DirectFinish™ technology applies sizing to each individual glass filament (not simply the surface of the yarn bundle like other glass fabrics), providing a superior interface between glass fiber and resin that yields improved electrical and thermal performance.

Smoother Coating

Verretec’s glass fabric is less porous than other glass fabric due to its FlatFiber™ construction and x-y uniformity, resulting in a consistently smooth surface, where pinholes and exposed fibers are minimized, and coating material usage can be significantly reduced.

 Improved Dimensional Stability

Verretec’s unique FlatFiber™ technology eliminates all yarn twist, resulting in a fabric with superior strength and uniformity, yielding improved, and more predictable, dimensional stability in rigid laminates.

Improved Drilling & Machining

Verretec’s FlatFiber™ construction minimizes weave knuckles and distributes glass fibers more uniformly, resulting in improved quality and efficiency in drilling and machining operations.

 Improved Resin-Reinforcement Interface

Verretec’s DirectFinish™ technology provides a superior interface between the glass fibers and the resin matrix, thereby helping to reduce the incidence of composite failures such as CAF failures in printed circuit boards.
